[PATCH v3 0/3] Add the clock stretching i2c property

[Andi Shyti]

Hello,

fter a discussion between Krzysztof and Ryan[1], it has become
apparent that the i2c binding is lacking the definition of a
property that needs to be added at a more generic level. This
property is also used by the mpc i2c controller, which has been
updated in the second patch.

The DTS schema change has been sent as github pull reqest[2].

Thanks Krzysztof and Chris for the reviews.

Thank you,
Andi

Changelog
=========
v2 -> v3:
 - Chris recommended to use of_property_read_u32() instead of
   of_get_property(). Because there were two use of it I added
   the suggested cleanup in a separate patch.
 - Added Chris r-b in patch 3.

v1 -> v2:
 - Removed the binding patch and send through a different channel
 - To ensure back compatibility, which was broken in v1, the
   legacy "fsl,timeout" has not been removed and marked as
   deprecated. In the driver the that property is checked anyway
   as a fallback in case the main i2c-scl-clk-low-timeout-ms is
   missing.

Andi Shyti (3):
  dt-bindings: i2c: mpc: Mark "fsl,timeout" as deprecated
  i2c: mpc: Use of_property_read_u32 instead of of_get_property
  i2c: mpc: Use i2c-scl-clk-low-timeout-ms i2c property
